WALL PAPER CLEANING DEVICE Filed April 24, 1940 Patented Sept. 23, 1941UNITED STATES PATENT OFFICE WALL PAPER CLEANING DEVICE John S. Lincoln,Des Moines, Iowa Application April 24, 1940, Serial No. 331,346

(oils-219) lever I1 is mounted on the shaft and provided 6 Claims.

There is in general use a Wall paper cleaning compound of a plasticnature, about the consistency of bread dough. It is generally used bygrasping it in an operators hand and wiping it over the paper to becleaned,and after one or two such operations it is kneaded by theoperators hands to withdraw the soiled surface into the mass. Thiskneading operation is necessarily hard and slow work.

The object of my invention is to provide a device of simple, durable andinexpensive construction in which a quantity of wall paper cleaner isplaced and a straight-edged portion thereof projected beyond the cleanerholder, and whereby the operator may grasp the handle of the cleaner andreadily and easily wipe a relatively large area of wall paper in asingle operation, and may conveniently and easily reach from a positionstanding on the floor of a room and clean all of the walls and ceiling.

More specifically, it is my object to provide a device of this class inwhich, when the projected portion of the cleaner has been used andbecome soiled, a very rapid and easy manual operation will move anotherportion of the cleaner to position to be projected beyond the holder andmove the previously soiled portion toward the center of the mass ofcleaner and apply a kneading operation to the cleaner and finallyproject a previously unused portion in a straight edged pattern beyondthe holder.

In the accompanying drawing- Figure 1 shows a perspective view of myimproved wall paper cleaning device;

Figure 2 shows a transverse sectional View of the same;

Figure 3 shows a detail transverse sectional View and illustrates theposition of the cleaning plastic within the holder when the compressingand mixing member has been moved to open position and before the plastichas been rotated within the holder; and

Figure 4 shows a longitudinal sectional view on the line 4-4 of Figure2.

My device comprises a cylindrical holder l having closed ends I I. Atone side of the holder there is formed a longitudinal slot at l2,through which the plastic cleaner is projected for cleaning purposes.Adjacent this slot I 2 there is a relatively large opening at l3 for usein inserting cleaning plastic into the holder. A handle I4 is fixed tothe holder.

Extended longitudinally through the central portion of the holder is ashaft I5 having at one with a spring actuated pawl It! to engage saidratchet for rotating the shaft. Fixed to the shaft on the interior ofthe holder adjacent each opening I3 is a cleaner compressing and mixingdevice comprising a curved wall 22 extended lengthwise of the holderthroughout substantially the entire length thereof, and when in closedposition, extended inwardly toward the longitudinal'center of theholder. At the inner end of this wall 22 is another wall 23 whichextends outwardly to the inner wall of the holder, and when this deviceis in its closed position, as shown in Figur 2, these two wallssubstantially cover the entire opening I3. -A handle 24 is fixed to thewall 23. r

In practical operation the handle 24 is moved to position for moving thewall 23 outwardly to position for uncovering the refilling opening I3.

When the plastic has been inserted in the holder the handle 24 is movedto position adjacent the handle I4 and they are shaped so that bothhandles may be conveniently grasped in an operators hand. When thiscompressing and mixing member has thus been forced into its closed Bythis compression method the outer surface of the projected portion ofthe plastic arranges itself along a substantially straight line, andwhen this is applied to wall paper and wiped over the wall paper it ispressed by the operator against the wall paper so that the plasticcleaner adapts itself to the contour of the paper and completely wipesthe entire surface covered by the wiping action. In practice, I havefound that when this has been done with one wiping operation, the paperis thoroughly cleaned and all of the dirt upon the paper adheres to theplastic cleaner.

After this operation the operator moves the handle 24 to positionbringing the wall 22 to a position substantially in line with the wallof the holder. This forms an open space, as shown at 25 in Figure 3,within the body of the plastic cleaner. Then the operator grasps thehandle end a ratchet wheel [6. A manually operated I1 and rotates theshaft l5. vWhen this has been werked into the mass of the cleaner;

done the plastic-engaging fingers 20 will grip the mass of material androtate it a small part of a revolution in the direction of the arrowsshown in Fig. 3. This will first withdraw the projected portion of theplastic cleaner due to the adhesive qualityof the cleaner, and move thesoiled portion of the plastic cleaner toward the right of the openingthrough which it was previously projected. Then, when the compressingand mixing member is again moved to its normal position, the previouslysoiled section of the cleaner will be moved inwardly" toward thelongitudinal center. of th holder. very quickly and easily performedbecause it requires only a small amount of power to open and close thecompressing and mixing member, and

only a slight amount of power to rotate the Obviously, this operationmay be shaft I5 the small part of a revolution. However, with these twoslight operations which must be performed after each wiping action ofthe. cleaner, the cleaning plastic isthoroughly kneaded and all of'thesoiled surfaces thereof are I have found n practice that with myimproved cleaning device a given quantity of the additional kneadingoperation is applied to the plastic compound by the kneading spiral Zl v'Devices of this class are commonly known to the trade aswallpapercleaners. They, however,

are useful in the cleaning of such things as win'dowshades, lamps,tapestries, tinted walls, pictures, kalsornined walls, etc.

I claim as my invention:

1.111 a wall paper v cleaning device, the combination of a holder for aplastic cleaner compound, said holder having a longitudinallyarrangedslot at one side, a handle for the holder, a rotatablecleaner-engaging member at thecentral portion of the holder having ahandle on the exterior of the. holder by which the mass of cleanerwithin the holder may be rotated to present new surfaces thereof to thesaid longitudinal slot,; said cleaner rotating device comprising arotatable shaft extended through the longitudinal central portion of-theholder, and fingers carried by the shaft and extended from the ends ofthe holder toward the transverse center thereof.

2. A wall papercleaning device, comprising a holder of cylindrical formhaving a longitudiment to position for clearing the opening, a poi tionof said compressing and mixing device'being extended inwardly from thewall of the 'holder toward the longitudinal center thereof,

and a handle fixed to the compressing and mixing device. 7

4. In a wall paper cleaning device, the combination of a holder for aplastic cleaner compound, said holder having. a longitudinally arrangedslot at one side, ahandle for the holder, a rotatable cleaner-engagingmember at the central portion of the holder having a handle on formingan open space in the mass of cleaner topermit ready withdrawal of thepreviously projected portion of the cleaner when the cleaner is rotated.I r

5.- A wall paper cleaning device, comprising a hollow receptacle for aplastic cleaning compound and formed with a longitudinal slot throughwhich a portion of the plastic may be projected, a plastic compressingmember connected t the receptacle and movable toward and from thelongitudinal center of. the receptacle for forcing'a'portion of theplastic to project through the slot when the compressing member is movedinwardly, and forming a longitudinal depression in the plastic material,and mean-s for rotatingthe mass of plastic material within thereceptacle whereby when the compressing mem her is moved outwardly andthe plastic material the receptacle, thereby forcing plastic materialatsaid depressed portion outwardly and effecting.

a kneading operation.
